Hairy cell leukemia(HCL) is a rare malignant hematological tumor. This article presents the diagnosis and treatment of a patient with recurrent HCL. This patient, a 51-year-old female, was diagnosed with HCL in June 2013 and subsequently received monotherapy with cladribine. Post-treatment evaluation indicated a partial remission. In November 2023, she experienced chest tightness and shortness of breath with ultrasound revealing a right-sided pleural effusion. A follow-up examination in February 2024 confirmed the relapse of HCL. She was then treated with a combination of vemurafenib and rituximab, which resulted in a rapid complete remission without minimal residual disease. This case provides valuable insights into the management of recurrent HCL.

DRG has been applied in most hospitals.The quality management of the first page of medical records,which is directly related to DRG grouping,has become an important part of hospital management.To some extent,the quality of the first page of medical records affects the inclusion of DRG,the payment of medical treatment,and the performance assessment and evaluation of hospital.Through examples,it focuses on the quality problems of the first page of medical records and its impact on DRG payment,analyzes the reasons leading to the cases of DRG not entered in the group or in the wrong group,and puts forward countermeasures to strengthen the quality manage-ment of the first page of medical records,in order to provide theoretical support and practical reference for hospital management and DRG payment management.

In fixed prosthodontics, clear exposure of the preparation margin is the prerequisite for obtaining accurate digital impressions and improving the marginal fit of restorations. To resolve the issues associated with the cord retraction technique, such as pain, acute injury, and prolonged procedural time, this study proposes a new technology for intraoral digital impression taking with pneumatic gingival retraction. The new scanning head blows a high-speed airflow that instantaneously separates the free gingiva, locally exposing the subgingival preparation margin. Combined with the farthest point preservation stitching algorithm based on the distance from the normal vector and high-speed laser scanning photography, it achieves global preparation edge data and gingival reconstruction, realizing painless, non-invasive, and efficient precise acquisition of the preparation margin. Using this new technique, a patient with a full porcelain crown restoration on a posterior tooth was treated. The digital impression revealed a clear margin of the preparation, and the crown made from this data has a good marginal fit.

Objective:To observe the changes of macular structure and microvessels in eyes with diabetes macular ischemia (DMI).Methods:A retrospective case study. From January 2023 to July 2023, 23 patients of 31 eyes diagnosed with DMI at Tangshan Ophthalmological Hospital were included in this study. Among them, there were 14 males with 23 eyes; Female cases with 8 eyes. Age were (59.5±4.6) years old. According to the DMI grading standard formulated by the research group for early treatment of diabetes retinopathy, the patients were divided into mild DMI group, moderate DMI group, and severe DMI group, with 8, 12, and 11 eyes respectively. The blood flow density (VD), perfusion area (FA), small vessel VD (SVD), inner retinal capillary plexus VD, FA, and outer retinal, choroidal, and ganglion cell complex (GCC) thickness within 1 mm of the macular fovea in retinal superficial vascular plexus (SVP)were measured using a scanning frequency light source optical coherence tomography instrument. The changes in macular structure and microvasculature in the affected eyes of different degrees of DMI groups were compared and observed. Inter group comparisons were conducted using one-way ANOVA or Kruskal Wallis H-test. Spearman correlation analysis was used to analyze the correlation between DMI severity and GCC, outer retina, choroid thickness, VD, FA and SVP VD, SVD and FA in inner retina. Results:The GCC ( F=70.670), outer retinal thickness ( H=12.393), VD ( F=105.506), SVD ( H=25.300), FA ( F=107.655), and VD ( H=24.098) and FA ( H=25.300) of the retinal SVP in the mild, moderate, and severe DMI groups were compared, and the differences were statistically significant ( P<0.05). There was no statistically significant difference in choroidal thickness ( H=2.441, P>0.05). Pairwise comparison between groups: VD, SVD, FA of GCC thickness and SVP, and VD of inner retina were statistically significant between severe DMI group and moderate DMI group, and between moderate DMI group and mild DMI group ( P<0.05). The thickness of outer retina was statistically significant between severe DMI group and moderate DMI group ( P<0.05). Inner retinal FA: there were statistically significant differences between severe DMI group, moderate DMI group and mild DMI group ( P<0.05). The correlation analysis results showed that GCC ( r s=-0.918), outer retinal thickness ( r s=-0.448), and inner retinal VD ( r s=-0.894) and FA ( r s=-0.918), as well as VD ( r s=-0.919), SVD ( r s=-0.924), and FA ( r s=-0.939) of retinal SVP, were all negatively correlated with the degree of DMI ( P<0.05). There was no correlation between choroidal thickness and degree of DMI ( r s=-0.081, P>0.05). Conclusion:The thickness of GCC, outer retina and choroid, the VD, SVD, and FA of the retinal SVP, the VD and FA of inner retina are all reduced in eyes with different degrees of DMI, while all of them are negatively correlated with the degree of DMI, except for choroid thickness.
